Given numbers are 161,840,864,868

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 161,840,864,868 is 21561120.

Find LCM of 161,840,864,868 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 3 x 7 x 23 x 5 x 36 x 31 = 21561120

Therefore, the lowest common multiple of 161,840,864,868 is 21561120.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

161 x 840 x 864 x 868 = 101423508480

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

161 : 1, 7, 23, 161

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,840,864,868, is 1.

Now, the common factors can be found like this.

161:7x 23

840:2x 2x 2x 3x 5x 7

864:2x 2x 2x 2x 2x 3x 3x 3

868:2x 2x 7x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 2x 3x 7x 7 = 4704

Therefore, the value for common factors is 4704.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 101423508480/(1x4704)

LCM = 101423508480/4704

LCM = 21561120

Thus, we can understand that the LCM of 161,840,864,868 is 21561120.
